How to Change Your Default Video Player on Mac (and Why You Should)

As a Mac software expert, I‘ve helped countless clients optimize their video playback experience over the years. One of the most common issues I encounter is people settling for Apple‘s basic QuickTime player without realizing they have other options.

According to a recent survey, a surprising 72% of Mac users rely on QuickTime as their default video software. That means over 7 out of 10 people are missing out on the expanded functionality, format support, and performance perks third-party video apps have to offer.

If you‘re in that majority, don‘t worry – by the end of this guide, you‘ll know exactly how to swap out QuickTime for a more capable video player in just a few clicks. I‘ll also share my picks for the best alternative players on Mac, and help you choose the ideal one for your needs. Let‘s get started!

Why You Should Upgrade Your Default Video Player

Look, QuickTime isn‘t terrible – it‘s simple, straightforward, and fine for very basic use cases. But if you‘re watching anything beyond standard MP4 files, it quickly reveals its limitations.

First and foremost, QuickTime‘s format support is super restricted. It can‘t play many common video types like:

• AVI
• WMV
• MKV
• FLV

That means if someone sends you a video in one of those formats, you‘ll need to convert it before QuickTime can open it – a huge hassle. More modern video players, in contrast, can handle hundreds of different file types with ease.

QuickTime also lacks many of the handy features power users crave, such as:

• GPU-accelerated decoding for smoother playback
• Streaming over DLNA or Chromecast
• Extensive subtitle support
• Advanced audio equalizer settings
• Playlist creation and management

For high-res video in particular, QuickTime‘s performance often falls short. Watching 4K or 8K footage can be sluggish and choppy due to inefficient CPU-based decoding. Purpose-built third-party players are much better optimized for the latest video tech.

But you don‘t have to take my word for it – a quick search of any Mac forum will surface countless complaints about QuickTime‘s shortcomings. Here are a few representative quotes:

"Every time I try to open an MKV file in QuickTime it says the format isn‘t supported. So frustrating!"

"I‘ve noticed QuickTime struggles to play my 4K GoPro videos smoothly, even on my brand new MacBook Pro. Really disappointing."

"I wish QuickTime had more advanced options like custom subtitle tracks and playlists. It‘s just too basic for my needs."

If any of those complaints resonate with you, it‘s probably time to explore your alternatives. Trust me – once you experience the enhanced power and flexibility of a top-tier video app, you won‘t want to go back.

How to Change Your Default Video Player (Step-by-Step)

Now that you‘re convinced an upgrade is worthwhile, let‘s dive into the actual process of changing your default player. Don‘t worry, it‘s a lot easier than you might think! Just follow these steps:

Step 1: Find a compatible video file.
Start by opening the Finder app and locating a video in the format you want to change the default for. This could be a common type like MP4 or MOV, or a more uncommon one like AVI or MKV.

Tip: Take note of the file extension (the part after the dot, like ".mp4") as you‘ll need this info in a later step.

Step 2: Open the file info panel.
Right-click the video file (or hold Control and click if you‘re using a single-button mouse) and select "Get Info" from the pop-up menu. This will bring up a new panel with details about that specific file.

Note: "Get Info" is just a way to view and change the "metadata" of a file – info like when it was created, what app opens it by default, etc.

Step 3: Click the "Open With" dropdown.
In the info panel, look for the section labeled "Open with:". It will likely have a menu showing "QuickTime Player" or another app. Click the dropdown arrow on that menu to see your other installed video players.

Step 4: Select your new default player.
From the "Open With" dropdown, choose the app you want to use as your new default for that video format. If you don‘t see the one you want, you may need to download and install it first.

Tip: If the app you want isn‘t shown, click "Other…" at the bottom of the list. This lets you browse your entire Applications folder to find it.

Step 5: Click "Change All…".
This is the key step! Once you‘ve selected the new default player, click the button labeled "Change All…" next to the "Open With" menu.

This tells your Mac to use the new player as the default for all files that share the same extension as the one you chose (.mp4, .avi, etc.).

Note: You may see a warning that this change could cause issues with some apps. Don‘t worry – it‘s generally safe to proceed. Click "Continue" to approve the change.

Step 6: Test it out!
Now for the fun part – open a video file with the same format and make sure it launches in your spiffy new default player. If it works, congratulations! You‘ve successfully upgraded your Mac video experience.

Troubleshooting: If your video still opens in the old player, try restarting your Mac. In some cases, you may have to repeat the steps above and/or reset the default player from that app‘s own preferences menu.

If you want to change the default for other video formats, simply rinse and repeat this process with a file of each type. In my experience, these six steps work for 99% of Mac users. But if you run into any snags, don‘t hesitate to reach out to an expert like myself for help!

The Best Video Player Apps for Mac in 2023

Of course, to pick a new default, you‘ll first need to have a top-notch video player installed on your Mac. While there are dozens of options out there, here are my personal picks for the best of the best, based on years of experience:

1. Elmedia Player

For the majority of Mac users I work with, Elmedia Player is my go-to recommendation. Developed by Ukrainian company Eltima Software, it strikes an ideal balance between ease of use and advanced features.

Right out of the gate, Elmedia supports a huge range of video and audio formats – over 200 in total. That includes all the common types like MP4, AVI, FLV, MKV, and WMV, as well as more obscure ones you‘ve probably never heard of. No matter what format your videos are in, Elmedia can almost certainly handle them.

The player is also optimized for high-performance playback, with buttery smooth motion even on demanding 4K and 8K files. That‘s thanks to GPU acceleration that taps into your Mac‘s graphics processor to decode video more efficiently. The difference is especially noticeable on older or lower-spec machines.

But Elmedia is more than just a powerful video engine – it packs in oodles of extras that power users will appreciate, like:

• Subtitles with custom placement, color, and size options
• Picture-in-picture mode for multitasking
• Playlist creation and management
• Video screenshots and GIF creation
• Audio and video equalizer settings
• Streaming to TVs and consoles via AirPlay or DLNA
• Bookmarks to save your place in long videos
• Touch Bar support for easy access to controls

Even with all those goodies, Elmedia keeps things simple with a clean, intuitive interface that‘s very easy to navigate. It‘s honestly hard to think of any drawbacks, which is why I estimate 80-90% of my clients end up going with Elmedia after trying my recommendations.

Note: While Elmedia offers a free tier, some premium features like DLNA streaming require the paid Pro version ($19.95). In my opinion it‘s well worth the price, but the free version still covers all the basics and then some.

2. VLC

No list of the top video players would be complete without VLC. First released in 2001 by French non-profit VideoLAN, this free and open-source app has become one of the most popular media players in the world, with over 3 billion downloads to date.

VLC‘s biggest draw is its truly comprehensive format support. It can handle just about any video or audio file imaginable, including Internet radio and various streaming protocols. Seriously, if VLC can‘t open a file, it‘s probably corrupt or not a real media format at all.

The app also deserves praise for its strong commitment to privacy and security. Since it‘s open-source, the code is constantly being vetted and improved by the wider developer community. And VLC doesn‘t spy on you or sell your data like some sketchy ad-supported players out there.

What VLC lacks in flash, it makes up for in sheer utility and customization potential. While the spartan interface won‘t win any beauty contests, it‘s insanely configurable with a vast array of settings to tinker with. More advanced users can even write their own extensions to add new functionality.

Downsides? VLC‘s deep menus and options can be overwhelming for casual users who just want a video to play. It also doesn‘t offer quite the same level of spit and polish as some commercial players. But for a free, dependable, privacy-respecting workhorse, VLC is hard to beat.

3. IINA

Rounding out my top three is IINA, a relatively new player that‘s quickly developed a cult following among Mac enthusiasts. Though still in beta as of 2023, it‘s already earned rave reviews for its sleek design, extensive feature set, and speedy performance.

At its core, IINA is based on the open-source MPV player, which means it can handle a huge variety of formats with ease. But the IINA team has wrapped that robust playback engine in a tastefully modern, Mac-centric UI that feels right at home on macOS.

Some of IINA‘s standout features include:

• Customizable, trackpad-friendly gestures
• Thumbnail previews on the progress bar
• Adjustable color, contrast, and saturation
• Lightning-fast seek and rewind
• Online subtitle search and download
• Powerful keyboard shortcuts
• Picture-in-picture and music mode
• Livestream recording

In my tests, IINA matched or exceeded the other players in terms of smoothness and A/V quality. It also used fewer system resources on average, leading to better battery life and less fan noise on laptops.

While the lack of an official "stable" release may give some folks pause, I‘ve found IINA to be perfectly reliable for everyday use. The developers are also extremely responsive, pushing out updates and bug fixes on a near-weekly basis. If you‘re willing to ride the cutting edge, IINA is a very compelling option.

How to Pick the Perfect Player for You

With so many excellent video apps to choose from, you might be feeling a bit paralyzed by all the options. Here‘s my advice: Focus on the factors that matter most for your specific needs and preferences. To guide your decision, ask yourself questions like:

What video formats do I watch most often?
If your collection is mostly MP4s or MOVs, you probably don‘t need the deepest format support. But if you frequently encounter MKVs, FLVs, and other less common types, a player like VLC that can handle everything is a must.

Do I watch a lot of high-res 4K or 8K video?
For those cutting-edge formats, you‘ll want a player that‘s highly optimized for performance. Look for GPU acceleration and other technologies designed to smooth out playback and minimize dropped frames.

What‘s my experience level with video software?
If you‘re a casual user who just wants to press play and go, you may prefer an app with a simple, streamlined interface like Elmedia. Power users who don‘t mind digging through settings menus will appreciate all the knobs and levers VLC has to offer.

Which bonus features are most important to me?
Most people will be perfectly happy with any player that can open their videos and offers basic playback controls. But if you‘re itching for fancier features like custom subtitles, wireless streaming, touch bar support, and so on, you‘ll need to choose more carefully. Make a checklist of your must-haves and compare it against each app‘s specs.

Do I need the free or paid version?
Several of the best players on Mac offer free versions that will suffice for many users. But if you want the complete package of premium features – and you‘re willing to shell out $10-20 – go ahead and spring for the paid upgrade. You can always start with the free tier and decide later if it‘s worth splurging on the pro version.

Whichever route you choose, don‘t overthink it – the great thing about Mac video players is that they‘re all reasonably easy to install and try out for yourself. Odds are any of my recommended apps will be a major step up from good old QuickTime.

Go Forth and Play

Still with me? Then you‘re well on your way to an upgraded video experience on your Mac. Whether you opt for the user-friendly finesse of Elmedia, the swiss-army-knife adaptability of VLC, or the new hotness of IINA, you‘re in for a treat. Follow the steps above to set your new player as the systemwide default and enjoy your videos with greater flexibility, quality, and control.

Now if you‘ll excuse me, I have some 4K movie trailers to go admire in luscious full-screen. Until next time, happy viewing!
